John S. Walters was a Staff Sergeant in the U.S. Army Air Forces, 357th Fighter Squadron, 355th Fighter Group. He entered the service from New Jersey.
At 3pm on 8 January 1945 a US Army Lorry carrying munitions[bombs] was involved in a road accident with a petrol tanker as it was passing Glebe Farm at the Flints in the village of Offley near Hitchin, Hertfordshire.
The drivers managed to evacuate nearby residents, but a bus from Luton came round the corner just as an explosion occurred, killing bus passenger Staff Sergeant Walters and injuring 21 others. The explosion was so severe that it made a crater on the road 50 feet wide and 14 feet deep.
He is now buried in Cambridge American Cemetery and Memorial, Coton, South Cambridgeshire District, Cambridgeshire, England.
